FISHES OF HAWAIIAN ISLANDS. 
295 
2 canines in each jaw, the upper pair wide apart, allowing the lower ones to fit between them; canines 
but little longer than the other teeth, which grow gradually smaller posteriorly; no posterior canines; 
preopercle not serrated; head naked; scales of breast smaller than those of body; lateral line abruptly 
bent downward below ninth dorsal ray; dorsal low, the longest (eighth) spine equal in length to 
snout, the rays about a tenth longer; longest anal ray 3.1 in head; spines slender, the third with a 
short cutaneous filament; caudal slightly rounded, 1.51 in head; pectoral 2.1 in head; ventral pointed, 
2 in head. 
Color in spirits (perhaps somewhat similar in life), head pale orange, upper part of opercle with a 
purple tint, the lower part silvery; nape purple; a narrow dorsal area, reddish orange fading ventrally 
to light orange; a rather indefinitely outlined, broad, pinkish stripe from opercle to base of caudal; 
lower part of body light orange; a reddish orange spot somewhat smaller than the pupil at lower edge 
of base of pectoral; each scale row with a narrow line of a darker shade than the color area on which 
it occurs; fins orange, the spinous dorsal suffused with red; scaled portion of caudal reddish orange. 
One specimen, the type, measuring 3.5 inches long, was collected at Honolulu by Mr. Berndt, No. 
50877, U. S. Nat. Mus. No other specimens known. 
Pseudojulis cerasina Snyder, Bull. U. S. Fish Comm., XXII, 1902 (Jan. 19, 1904), 528, Honolulu. 
Genus 156. THALASSOMA Swainson. 
Body oblong or elongate, moderately compressed, covered with large scales; lateral line continuous; 
head scaleless; a slight sheath of scales along base of dorsal; no posterior canine; dorsal spines slender, 
the number always 8; anal spines 3, the first very small; lower pharyngeals essentially as in Halichceres. 
Beautiful fishes of the coral reefs and warm currents, the coloration largely deep green or blue.
